One of the benefits of a geothermal heating and cooling system for a home is the number of years it can last without needing serious repairs. The ground loops can endure for more than 50 years, while the indoor heat pump elements are often in solid shape for more than 20 years. But repair needs are still a possibility, even with the most stringent annual maintenance. You should always turn to geothermal professionals when you need fixes for your ground-source heat pump, since they can ensure that the work is done quickly and correctly.

Some occasional repair needs for a geothermal heat pump
- Sealing ground loop leaks: The plastic loops that carry the refrigerant (usually a mixture of water and antifreeze) through the ground and to the heat exchanger in the heat pump are made of tough material that resists corrosion and leaking. Nonetheless, leaks can sometimes occur, and if you detect a loss of heating or cooling power from your geothermal system, this leaking might be the issue. Geothermal specialists can pinpoint where the leaks are occurring using a dye inserted into the system, and afterwards they will use targeted excavation to reach the damaged loop and seal it with the least amount of disruption to your property.
- Acid flushing the loops: Some ground-source heat pumps use an open loop system where they bring in water from the municipal system. This outside water can carry deposits that will build up inside the loops and cause a spike in water pressure. Technicians can easily remedy these with an acid flush sent through the loops to clear them out.
- Repairs to the heat exchanger: The antifreeze solution in the ground loops is not what runs through the indoor heat pump to either absorb or release heat. Instead, the antifreeze goes into a heat exchanger and adds or absorbs heat from standard refrigerant, and this refrigerant is what enters the heat pump’s coil. Problems in the heat exchanger will prohibit the system from working correctly and will require that professionals apply repairs.
There are also standard repairs that any heat pump may need: defrosting the coils, recharging refrigerant, replacing capacitors and motors, etc. Geothermal specialists are familiar with all of these repairs and will know how to get to the bottom of the problem that’s afflicting your system.
A geothermal heat pump is one of the best investments you can make for home comfort: don’t let it spoil because you let a repair need go without attention. Contact Advantage Airtech in Toronto, ON for geothermal system repair whenever you require it.
